Image Haze Removal Based on Superpixels and Markov Random Field
Image haze removal is critical for autonomous driving. However, it is a challenging task for the existing image dehazing algorithms to eliminate the block effect completely and handle objects similar to light (such as snowy objects and white buildings ...

Superpixel Segmentation: An Evaluation
In recent years, superpixel algorithms have become a standard tool in computer vision and many approaches have been proposed. However, different evaluation methodologies make direct comparison difficult. We address this shortcoming with a thorough and fair comparison of thirteen state-of-the-art superpixel algorithms.

Image Segmentation via Clustering Superpixels
This paper presents a method for image segmentation by clustering superpixels based on histogram dissimilarity. A superpixel is a tiny image fragment which contains the edge or boundary information of sub-regions in the image. Each sub-region consists of

Double-Branch Multilevel Skip Sparse Graph Attention Network for Hyperspectral Image Classification
Graph neural networks (GNNs) offer a potent framework for learning and representing data with graph structures. In the context of hyperspectral images (HSIs) classification tasks, GNNs have been successfully employed. Among the diverse variations of GNNs,

V.: SEEDS: Superpixels extracted via energy-driven sampling
. Superpixel algorithms aim to over-segment the image by grouping pixels that belong to the same object. Many state-of-the-art superpixel algorithms rely on minimizing objective functions to enforce color homogeneity.

SuperPatchMatch : Un algorithme de correspondances robustes de patchs de superpixels
Les superpixels sont devenus très populaires dans de nombreuses applications de vision par ordinateur. Néanmoins, ils restent sous-exploités du fait de l'irrégularité des décompositions qui diffèrent selon les images. Dans ce travail, nous introduisons d'
